I mean FTP port 20,21. Please see my configuration below:

Topology:
LAN1----R1(s0/1/0)---------128kbps--------(s0/1/0)R2--LAN2
LAN1: 172.16.1.0/24
LAN2: 172.16.2.0/24
R1-R2: 192.168.1.0/24

LAN1 and LAN2 using two method to send file, using port 445 (microsoft) and
23(FTP), I want to priority sending at port 23 over port 445, so I
configuration like this:
- R1:
! access 100 match FTP traffic
(config)# access 100 permit tcp any any eq 20 (config)# access 100 permit
tcp any any eq 21 (config)# access 100 permit tcp any eq 20 any (config)#
access 100 permit tcp any eq 21 any

(config)# class-map CLASS_FTP
(config-map)# match access-group 100
(config)# policy-map POLICY_FTP
(config-policy)# class CLASS_FTP
(config-policy-class)# priority 200

(config)# policy-map POLICY_DEFAULT
(config-policy)# class class-default
(config-policy-class)# shape average 128000 ! shape to 128kbps
(config-policy-class)# service-policy POLICY_FTP (config)# int se0/1/0
(config-if)# service-policy output POLICY_DEFAULT

But when I use PC1(belong to LAN1) send the same file to PC2(belong to LAN2)
using: FTP and 445 (microsoft), the FTP do not get priority over microsoft
(port 445) I use this command on R1 to check:
#show policy-map int se0/1
Is show that FTP hit the policy! It mean it match the policy POLICY_FTP but
do not get priority!?????

If that's what you have configured, that's the simple part. FTP is port 21
(and 20 for control). Port 23 is telnet. :)

The first, thanks Scott Morris!
The second, I have this topology:
LAN1----R1(s0/1/0)---------128kbps--------(s0/1/0)R2--LAN2
LAN1: 172.16.1.0/24
LAN2: 172.16.2.0/24
R1-R2: 192.168.1.0/24

(config)# class-map CLASS_FTP
(config-map)# match access-group 100
(config)# policy-map POLICY_FTP
(config-policy)# class CLASS_FTP
(config-policy-class)# priority 200

Queuing is ALWAYS outbound. QoS SHOULD be designed for end-to-end
functionality (real-life), although implemented at individual points.

In the lab exam, you only do what is asked. Even in real-life, there may be
situations where you don't need to worry about it (remember, no congestion =
no queuing). But if you get something on your lab that refers to a
conversation between LAN1 and LAN2, I personally would implement the QoS on
both routers.

Overconfiguration (unless prohibited) is not penalized.

I also think like you, Alexei. But in some IEWB LAB, it just use LLQ for one
side! So I confuse this too much!

I think yes, you should. Queuing generally works in outgoing direction, so
having it set up for one side only would improve a quality for that side
while opposite stream (within the same conversation) might suffer with lack
of LLQ.
